Web1 de nov. de 2024 · Capacitive loads can make chopper-stabilized op amps unstable. In olden days, when op amps used ±15 V supplies and input/output signals were ±10 V, we had few problems with input/output limitations. Our op amps output impedance (Zo), small-signal AC impedance, open-loop output impedance was resistive: 25 Ω to 50 Ω. Web22 de jan. de 2016 · Op amps are not usually designed to drive a large capacitive load. The capacitance interacts with the open-loop output impedance, R O, of the amplifier to introduce a pole, fp O1, in the amplifier’s open-loop gain curve, as shown in Figure 3. This pole causes excessive phase shift in the feedback loop, severely degrading phase margin.
